Diabetes-related intestinal region-specific thickening of ganglionic basement membrane and regionally decreased matrix metalloproteinase 9 expression in myenteric ganglia

Figure 2 Representative fluorescent micrograph of a paraffin section of myenteric ganglia from the ileum of a control rat after matrix metalloproteinase 9-tissue inhibitor of metalloproteinase 1 double-labelling immunohistochemistry. A: Matrix metalloproteinase 9 immunoreactivity is indicated in red; B: tissue inhibitor of metalloproteinase 1 immunoreactivity is shown in green; and C: The merge is depicted on. Scale bar: 20 μm. MG: Myenteric ganglia; LSM: Longitudinal smooth muscle layer; CSM: Circular smooth muscle layer; arrows-blood vessels.
